Struct MappedMutexGuard

pub struct MappedMutexGuard<'a, M, T>
where
    M: RawMutex,
    T: ?Sized,
{ /* private fields */ }

A handle to a held Mutex that has had a function applied to it via MutexGuard::map or MappedMutexGuard::map.

This can be used to hold a subfield of the protected data.

Implementations

impl<'a, M, T> MappedMutexGuard<'a, M, T>
